Well-architected best practices for software supply chain security

This AWS blog post outlines best practices, aligned with the AWS Well-Architected Framework, to protect against software supply chain attacks like Shai-Hulud. Key recommendations for package consumers include: using temporary credentials and least privilege to limit exposure; implementing defense in depth with multi-factor authentication, multi-party approval workflows, and artifact signing (using AWS Signer) to prevent sprawl; centralizing dependency management with AWS CodeArtifact and Amazon ECR; scanning dependencies throughout the lifecycle with Amazon Inspector and community threat intelligence (including MAL-IDs); and configuring robust logging and monitoring with CloudTrail, GuardDuty, and Security Hub to detect anomalous activity. The post emphasizes layered controls to reduce risk from compromised credentials and malicious packages.

Prompt Engineering Demands Rigorous Evaluation

In the blog post “Prompt Engineering Requires Evaluation” on the Shostack + Associates website, the author argues that treating prompts for large language models (LLMs) merely as creative artefacts is insufficient. Engineering prompts properly demands structured evaluation frameworks — what the AI community calls “evals” — to test which prompt versions work better, with which models, and under which conditions. The post highlights that simply assuming a prompt is “good enough” creates risks when LLMs are integrated into production systems (e.g., for threat modeling). It advocates for measuring prompt performance, variation effects, and tool-chain dependencies (model, context, ancillary materials).  Ultimately the message is: prompt engineering should borrow disciplined practices from software engineering (versioning, testing, benchmarking) rather than relying on informal experimentation.  https://shostack.org/blog/prompt-enignieering-requires-evaluation/
